** Description changed: Installed focal-iotg-core-20210722.img on the TGL-H. Boot process stops after it gets errors from TPM and fails to start an emergency shell (see screen shot.) I also tried to go into the BIOS to clear TPM, as this worked for the EHL board but it still behaves the same. Once it reaches this point, the keyboard is unresponsive (cannot soft reboot, get to a terminal window, etc.) Error message when installing uc20 with secure boot and TPM enabled: the-tool[336]: error: error locking access to sealed keys: cannot execute hash sequence: TPM returned an invalid response for command TPM_CC_EventSequenceComplete: cannot unmarshal response parameters: cannot unmarshal argument at index 0: cannot process list type tpm2.TaggedHashList: cannot process element at index 3 from list type tpm2.TaggedHashList: cannot process custom type tpm2.TaggedHash, inside container type tpm2.TaggedHashList: cannot determine digest size for unknown algorithm TPM_ALG_SM3_256 + + https://cs.opensource.google/go/x/crypto
